Answer:

355 senior citizen tickets were sold.

Step-by-step explanation:

Assuming a to the the ticket of adults and s to be the ticket of senior citizens, we can write two equations as:

[tex]a +s=465[/tex] --- (1)

[tex]23a+13s=7145[/tex] --- (2)

From equation 1, [tex]a=465-s[/tex].

Substitute [tex]a[/tex] in equation 2 to get:

[tex]23 (465-s) + 13s = 7145[/tex]

[tex]10695 - 23s +13s =7145[/tex]

[tex]-10s = -3550[/tex]

[tex]s = 355[/tex]

Therefore, there were 355 senior citizen tickets sold.

Step-by-step explanation:

Answer: 1.60x + 1.75y is less than or equal to 10

Step-by-step explanation:

Since the strawberries cost $1.60 per pound, it would be x pounds times $1.60 for the total cost of strawberries. Since the raspberries cost $1.75 per pound, it would be y pounds times $1.75 for the total cost of the raspberries. The total cost of both, or 1.60x + 1.75y, must be equal to or less than 10 because she cannot spend over 10 dollars.

The situation can be represented by the equation 1.60x + 1.75y = 10, where x represents the pounds of strawberries and y represents the pounds of raspberries. To find out how many pounds of strawberries and raspberries Joy can buy, we can rearrange the equation and solve for x and y.

The situation can be represented by the equation 1.60x + 1.75y = 10, where x represents the pounds of strawberries and y represents the pounds of raspberries. To find out how many pounds of strawberries Joy can buy, we can rearrange the equation to solve for x: x = (10 - 1.75y) / 1.60. Similarly, to find out how many pounds of raspberries Joy can buy, we can rearrange the equation to solve for y: y = (10 - 1.60x) / 1.75.

Answer:

the answer is false.

Step-by-step explanation:

Answer:

False

Step-by-step explanation:

2x+y=3

⇒ This equation can be written in the form of y = mx + c where m is the slope, c is the y-intercept and x and y are x and y coordinates respectively of the point where the the line passes.

2x+y=3

y = -2x + 3.

If the line passes through the origin (0,0), then c = 0. This is not the case in our eqation.

Again if the question passes through the origin, by substituting the point (0,0) in the question it would satify it.

2x+y=3  ⇒ 2(0) + 0 = 3

                     0 + 0 ≠ 3

                      0 ≠ 3

The solution to the system of equations is (12, 30).

Option B is the correct answer.

Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.

We also find the solution in a system of equations using the substitution or elimination method.

Example:

2x + 4 = 8

The solution is x = 2.

We have,

To solve the system of equations using the substitution method,

We solve one equation for one of the variables and substitute the expression into the other equation.

Let's solve the first equation for y:

y = 2x + 6

Now, substitute y = 2x + 6 into the second equation and solve for x:

3x - y = 6

3x - (2x + 6) = 6

3x - 2x - 6 = 6

x = 12

Now that we have found x, we can substitute it back into either of the original equations to find y.

Let's use the first equation:

y = 2x + 6

y = 2(12) + 6

y = 30

Final answer:

To find out how far Sarah can drive on a full tank of gas, the correct proportion is '77/3.6 = x/15'. This compares the known miles driven to gallons used, scaled up to a full tank of 15 gallons, representing the distance with 'x'. So the correct option is d.

Explanation:

The student is working on solving a proportion problem related to fuel consumption and driving distances. To find out how far Sarah can drive her car on a full tank of gas, we need to set up a proportion that compares miles driven to gallons used, and then scale it up to a full tank of gas.

Since Sarah drove 77 miles on 3.6 gallons of gas, we can compare this to a full tank of 15 gallons to find the total distance she can drive, represented by 'x'. The correct proportion is 77 miles to 3.6 gallons as 'x miles' is to 15 gallons.

The correct proportion is d. 77/3.6 = x/15, as it reflects the direct relationship between miles driven and gallons of fuel. When the gallons are increased from 3.6 to 15, we expect the miles that can be driven to increase proportionally.

Replace f(x) with y

[tex]y= x^2 -1[/tex]

Replace x  with y  and y with x

[tex]x= y^2 -1[/tex]

Solve for y

add 1 on both sides , [tex]x+1= y^2[/tex]

To remove square , take square root on both sides

[tex]f^{-1}(x)[/tex]

Step 1: Replace [tex]f^{-1}(x)[/tex] with y

[tex]y=x^2-1[/tex]

Step 2: Switchx and  y

[tex]x=y^2-1[/tex]

Step 3: Solve for y

[tex]x=y^2-1[/tex]

[tex]x+1=y^2-1+1[/tex]

[tex]x+1=y^2[/tex]

[tex]y^2=x+1[/tex]

take square root of both sides

Answer:

C and D

Step-by-step explanation:

The Middles were the same length and the side of the alligator are slightly longer.

The correct options are:

C.  Center-- The crocodiles have a greater median length than the alligators.

D.   Spreads--  The lengths of the alligators are more spread out.

Median of the data--

The median is the central tendency of the data and it always exist in the middle of the data.

By looking at the data.

We observe that the Median of the data :

Crocodile lie at : 17

and that of the alligator lie at : 9

Hence, the median for the crocodile is more than for the alligators.

Spread--

The spread in the data means how far the data points are from the center of the data i.e. mean or median.

By looking at the data crocodile we observe that all the data points are close to the median.

whereas in the data alligator one of the data point is far from the median.

Hence, the spread in case of alligator is more as compared to that of crocodiles.

Final answer:

The question compares two breathing rates: 15 breaths every 36 seconds and 90 breaths every 3 minutes. When converted to breaths per minute, the rates are 25 breaths/minute and 30 breaths/minute respectively, indicating that they are not equivalent.

Explanation:

The question asks whether 15 breaths every 36 seconds and 90 breaths every 3 minutes represent an equivalent rate of breathing. To solve this, we need to determine if the two rates are the same when converted to a common time unit.

First, let's convert 36 seconds to minutes: 36 seconds is 0.6 minutes (since 1 minute is 60 seconds). Next, we calculate the breathing rate per minute for the first scenario by dividing the number of breaths by the number of minutes: 15 breaths / 0.6 minutes = 25 breaths/minute.

Now let's look at the second rate of 90 breaths every 3 minutes. This can be simplified by dividing the number of breaths by the number of minutes: 90 breaths / 3 minutes = 30 breaths/minute. Clearly, 25 breaths/minute is not equivalent to 30 breaths/minute. Therefore, 15 breaths every 36 seconds and 90 breaths every 3 minutes are not equivalent rates of breathing.

Answer:18 1/12

Step-by-step explanation:i first added the whole numbers 12 and 5 to get 17; i then addled 1/4 and 5/6; i did this by finding a common denominator of both fractions and converted them into 6/24 and 20/24; i added them to get 26/24 which simplifies to 1 and 2/24, which equals 1 1/12; i added 1 to 17 and got 18, then added 1/12 to get 18 1/12

The sum of 121/4 and 5 5/6 is found by converting the mixed number to an improper fraction, finding a common denominator, adding the fractions, and simplifying if possible. The final answer is 433/12, which is already in its lowest terms.

The question asks for the sum of the numbers 121/4 and 5 5/6 reduced to the lowest terms. To answer this, we must first convert the mixed number to an improper fraction and then add it to the other fraction. Here's how to do it step by step:

Convert 5 5/6 to an improper fraction: 35/6.

Add 121/4 to 35/6. To do this, find a common denominator, which would be 12 in this case.

Convert both fractions to have the common denominator: 121/4 becomes 363/12, and 35/6 becomes 70/12.

Add the two fractions: 363/12 + 70/12 equals 433/12.

Reduce the fraction if possible. In this case, 433/12 is already in its lowest terms.

Therefore, the sum of 121/4 and 5 5/6 reduced to lowest terms is 433/12.

Answer:

658.24 m

Step-by-step explanation:

Let A be the point from where Elton started. Connect points A and C, you get triangle ABC with AB=500 m, BC=350 m and m∠B=100°. Use the cosine rule to determine the length of the segment AC:

[tex]AC^2=AB^2+BC^2-2\cdot AB\cdot BC\cdot \cos \angle B,\\ \\AC^2=500^2+350^2-2\cdot 500\cdot 350\cdot \cos 100^{\circ},\\ \\AC^2=250000+122500-350000\cdot (-0.174),\\ \\AC^2\approx 433276.8622,\\ \\ AC\approx 658.24\ m.[/tex]

Answer:

658.24 m

Step-by-step explanation:

The figure makes a triangle with vertices abc.

Where ab = 500 m

           bc = 350 m

The angle abc = 100°

Using the cosine rule we can find the distance ac.

ac² = 500²+350² - 2×500×350×cos100°

      = 372,500 - -60,776.86

      = 433,276.86

ac = √433,276.86

    = 658.24 m

The point-slope form:

[tex]y-y_1=m(x-x_1)[/tex]

We have the slope m = 4 and the point (2, 1). Substitute:

[tex]y-1=4(x-2)[/tex]      use distributive property

[tex]y-1=(4)(x)+(4)(-2)[/tex]

[tex]y-1=4x-8[/tex]        add 1 to both sides
